William has been proven by DNA and genealogical research to be a descendant of Henry Culpepper of Chattahoochee Co., GA. DNA has also proved that Henry is a grandson of James Culpepper of Nash and 2-great-grandson of Henry Culpepper of Lower Norfolk, VA.

He, as a family member, accompanied Henry Culpepper of Chattahoochee Co., GA in relocating on 13 Feb 1854 at Chattahoochee Co., Georgia; The Culpeppers did not literally relocate but were living in the southern part of Muscogee County in 1854 when that part of the Muscogee was split off to form Chattahoochee County, with Cusseta as its county seat.

From Susan Tompkins:It appears William T.A.L. and Mariah Louisa Wall Culpepper moved from Chattahoochee County, Georgia to Phenix City, Alabama sometime after Sallie was born 16 MAY 1872 and before Frances Rowena 'Roey' was born on 14 AUG 1874.

After the turn of the century and up until the early 1930s what is now known as 'Phenix City' was called 'Girard'. Also you literally went from one street to the next and it would go from being Lee County to Russell County. That was why if I knew someone was born in Phenix City – Iisted them as Lee or Russell. Today, the location of their births would be Russell County.9

William T. A. L. is the name on his marriage license. I noticed it was reported as 'William Culpepper' on the 1850 and 1870 census and as 'WM' on the 1900 census - with the W and M being written so close that when it is translated to a typed version it is displayed as 'W M'. Also on the death index and where Mariah applied for his Confederate pension - of $1.50 - it is shown as 'W M'.
